This study aimed to compare the values of forearm oxygenation kinetics measured by the NIRO-300 and PSA-IIIN instruments. Sixteen healthy males performed a maximal sustained gripping test for 3min using both instruments. The cross correlation coefficient of the sustained gripping value between sessions measured by both instruments was very high (rxy=0.999), and the decreasing trends agreed well. There were differences in the changes in the patterns of oxygenation kinetics between both the NIRS instruments for the first 30s after the onset of gripping. However, the cross correlation coefficients of these kinetics were very high (rxy=0.918-0.965), and the changing patterns (increase, decrease, and constant) were similar. In conclusion, the PSA-IIIN can be used to evaluate muscle oxygenation kinetics just as well as the NIRO-300, and it is an excellent choice both in terms of price and portability.
